DP83TC811S-Q1: [DP83TC811S T1 PHY] Does it mean RGMII works when PCS loopback works?

Hi , Experts  :

as title description.

Our SoC (TDA4) use RGMII to communication with DP83TC811.

I set DP83TC811 works in PCS loopback mode, T1 cable disconnect, debug message show successful works in PCS mode.

My question is :

Does it mean RGMII interface also have TX/RX test data stuff to DP83TC811?

Is RGMII interface works?

Many Thanks
